Description
Technical Field
The invention relates to a ceramic moxibustion composite energy-saving material, in particular to a graphene ceramic moxibustion composite energy-saving material and a preparation method and application thereof.
Background
The urban living environment has fast rhythm, less movement of people and high working pressure, which leads to the sub-health state of the body. Particularly, the long-time sitting in the air-conditioning environment, the lack of perspiration and toxin expelling, and the long-time sitting can cause various diseases of the body. The thermotherapy is a green health therapy which is internationally recognized, and can achieve the effects of dispelling dampness and expelling cold, beautifying muscles and slimming and dredging channels and collaterals by activating cells of the whole body and promoting yang qi of the body.
A plurality of warming devices made of natural mineral ceramic materials, including sand therapy, salt therapy, jade therapy, porcelain moxibustion and the like, have become good ways for urban people to relieve pressure, eliminate dampness and cold. These warming devices are methods for alleviating symptoms of diseases by the combined action of pressure and far infrared rays through the heat transfer action of hot sand, salt or jade, and at the same time, by the energy permeation of heat and minerals. The sand, salt, jade and mineral warm heat can promote the blood circulation of the human body buried therein to accelerate, thereby dredging the channels and collaterals and eliminating wind, cold, dampness, evil, heat, stasis, blockage and toxicity in the human body so as to realize the treatment of various rheumatic joint diseases and chronic diseases such as neck, shoulder, waist and leg pains and the like.
At present, sand therapy, salt therapy, porcelain moxibustion and the like are used for physical therapy in a groove bed mode, and electric heating films are adopted at the bottom and the periphery of the groove bed to heat materials in a groove and keep a certain temperature. Each tank bed uses electricity about 10-15 degrees every day (working time is about 12 hours), and the electricity is about 5000 degrees in one year. If each business storefront is calculated according to two groove beds, ten thousand degrees of electricity are needed one year, and great operation cost is brought to operators. Meanwhile, the temperature of the grooved bed is slowly raised in the heating process, so that inconvenience is brought to health-preserving store operators.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide the graphene ceramic moxibustion composite energy-saving material which is rapid in temperature rise, has a self-heat storage function, can save more than 20% of electricity, releases high-frequency ultrasonic waves, has an antibacterial and bacteriostatic function, and is a natural, environment-friendly, energy-saving and consumption-reducing new material.
The invention also provides a preparation method thereof, which has simple process, reduces environmental pollution and saves energy; the invention also provides the application thereof.
The graphene ceramic moxibustion composite energy-saving material is prepared from the following raw materials in percentage by weight: 60-80% of heat storage material, 15-30% of high-frequency material, 1-5% of antibacterial material, 0.1-3% of pore-forming material and 0.1-3% of binding material;
wherein,
the heat storage material is prepared from graphene, kaolin, sepiolite and alumina;
the high-frequency material is prepared from terahertz powder, stone needle powder, jade powder, far infrared powder and germanium powder;
the antibacterial material is prepared from nano zinc oxide, silver powder and copper-zinc alloy;
the pore-forming material is made of activated carbon powder;
the binding material is made of sodium metasilicate.
The heat storage material is compounded by kaolin, sepiolite and alumina with natural micropore structures. The alumina is a material with a heat storage function, and the heat storage points of the alumina powder body are combined with the microporous channel by virtue of the large specific surface area of the microporous structure and the characteristics of the microporous channel, so that the wide heat storage distribution effect is better. Graphene has a good far infrared characteristic and also has a good heat storage function. The added graphene powder can enter a nano channel with a natural microporous structure to form an internal and external heat storage channel with aluminum oxide, so that the heat storage function of the material is enhanced in a synergistic manner.
The high-frequency material adopts materials such as terahertz materials, natural stone needles, jades and germanium powder with energy characteristics such as far infrared rays, not only improves the functions of permeability and blood circulation promotion to the health in the porcelain moxibustion process, but also can increase heat storage distribution in cooperation with the heat storage material, and plays a better heat storage function.
The antibacterial material adopts zinc oxide, silver powder and copper-zinc alloy materials, and the copper and the zinc have different potentials to form a primary battery effect. The copper, zinc, silver powder and other materials not only have good antibacterial and bacteriostatic functions, but also can improve the metal component percentage in the whole material, and promote the metal component percentage and the aluminum oxide in the heat storage material in a synergistic manner, so that the temperature raising speed is accelerated, and the heat storage function is enhanced.
Wherein:
the heat storage material is prepared from the following raw materials in percentage by weight: 0.1-3% of graphene, 20-45% of kaolin, 30-55% of sepiolite and 20-45% of aluminum oxide.
The high-frequency material is prepared from the following raw materials in percentage by weight: 10-30% of terahertz powder, 10-30% of stone needle powder, 5-20% of jade powder, 5-20% of far infrared powder and 2-20% of germanium powder.
The antibacterial material is prepared from the following raw materials in percentage by weight: 50-75% of nano zinc oxide, 0.5-5% of silver powder and 20-48% of copper-zinc alloy.
The preparation method of the graphene ceramic moxibustion composite energy-saving material comprises the following steps:
1) firstly, mixing kaolin, sepiolite and alumina, and grinding the mixture to the granularity of 100-500 meshes to prepare a composite material A;
2) mixing graphene and the composite material A, baking for 1-5 hours at the temperature of 100-300 ℃, and grinding until the granularity is 50-500 meshes to obtain a composite material B;

5) and (3) airing the spherical particles for 10-50 hours in the sunshine, and sintering for 3-10 hours in a kiln to obtain the product.
Wherein:
in the step 5), the sintering temperature is 100-.
Mixing the graphene with the composite material A, and baking the mixture at the low temperature of 300 ℃ for 1 to 5 hours at 100 ℃. Graphene is uniformly dispersed into the micropore channel mainly through a low-temperature baking process. Because the temperature resistance of the graphene is not high, the baking temperature is not higher than 300 ℃.
And the inorganic binder is adopted, so that the environment is protected. In order to enhance the bonding effect, the composite material needs to be aired in the sun for 10 to 50 hours to ensure that the bonding agent is fully bonded and fused with the composite material. Then sintering for 3-10 hours at a low temperature of 100-500 ℃. The low-temperature sintering process can enable the graphene to be dispersed more uniformly in the nano-channel of the microporous material, and the graphene has better heat storage performance in cooperation with other materials.
